Power head or power arm assembly for linear reciprication of windshield wiper blade

A system comprising a Power Head assembly and Power Arm assembly, the system configured to cause a windshield wiper blade of a vehicle to reciprocate linearly along the windshield wiper blade for removing ice or debris from a windshield of the vehicle,

• the Power Head assembly comprising:
• a first motor having a shaft configured to rotate when the first motor is activated;
• a first converter coupled to the shaft of the first motor and configured to convert rotational motion of the shaft to reciprocating linear motion;
• a weatherproof housing configured to house the first motor and an inner portion of the first converter;
• a receptacle configured to receive a first end of a windshield wiper arm of the vehicle;
• a fastener configured to attach an outer portion of the first converter directly or indirectly to the windshield wiper blade, causing the windshield wiper blade to reciprocate in a direction that is parallel to the windshield wiper blade when the first motor is activated;
• and
• a controller configured to control the first motor, the controller comprising:
• one or more input power lead connectors configured to connect to an electrical system of the vehicle for receiving power from the electrical system of the vehicle;
• one or more output power lead connectors configured to connect to the motor to supply the power received from the electrical system of the vehicle to the motor;
• a control circuit configured to generate a control signal for controlling the power supplied to the first motor;
• and
• a protective circuit, comprising:
• a current sensor configured to detect a current flowing through the first motor, wherein when the current flowing through the first motor is greater than a threshold, the controller cuts off the power of the first motor for at least a predetermined period;
• and
• a current blocker configured to cut off the power of the first motor;
• the Power Arm assembly comprising:
• a motorized pivot configured to cause the windshield wiper blade to sweep in an arcing motion across the surface of the windshield about the motorized pivot;
• a power wiper arm, the power wiper arm comprising:
• a drive motor configured to cause the power wiper arm to reciprocate linearly along the power wiper arm, the drive motor comprising:
• a second motor having a shaft configured to rotate when the second motor is activated;
• and
• a second converter coupled to the shaft of the second motor and configured to convert rotational motion of the shaft of the second motor to reciprocating linear motion;
• a wiper arm base configured to couple the power wiper arm to the motorized pivot, the wiper arm base comprising:
• a switching mechanism configured to switch the power wiper arm between an operating position and an off position, wherein
• when the power wiper arm is in the operating position, the windshield wiper blade touches the windshield and applies pressure onto the windshield, and
• when the power wiper arm is in the off position, the windshield wiper blade is lifted away from the windshield.
